Public bug reported:
Immediately after connecting to a PPTP VPN /etc/resolv.conf contains the
DNS servers sent by the remote PPTP connection, and only those entries.
The previous entries sent by DHCP are removed. After a few minutes, the
PPTP entries are removed and replaced with the original DHCP entries.
This is broken.
The cause I believe is that PPTP itself replaces /etc/resolv.conf, but
then dhclient refreshes it periodically.
Optimally, NM would handle the creation of /etc/resolv.conf, taking both
the DHCP and PPTP entries and combining them. Probably in DHCP, PPTP
order.
